The Analysette 22 MicroTec Plus is the latest generation of this company’s particle measurement technology. The instrument covers a range of 0.08 to 2,000 µm with a resolution of up to 108 measuring channels. The wet dispersion unit is equipped…
The Helical Dryer series HD was designed to meet the requirements of multipurpose production, as specified by a study group that included major European pharmaceutical manufacturers. The dryer incorporates an optimized mixing assembly, which features a mechanical seal (without product…
Electromechanical (EM) pumps are widely used in wastewater and sewage treatment, chemical and ceramic industries, mining, power plants, marine and offshore applications. With RAN EM diaphragm pumps, capacities up to 30 m³/h can be transferred. Body material options are aluminum,…
Friction Factor Fluid flowing through pipes experiences resistance due to viscosity, turbulence and roughness of the pipe surface. The Darcy-Weisbach Equation (1) is commonly used for the analysis of steady-state, Newtonian-fluid flow inside pipes. It summarizes the relations between frictional…
This brief introduction to nanotechnology provides a basic understanding to those new to the field Most chemical engineers and chemists are aware of the recent excitement generated by nanotechnology, but many may wonder what all the fuss is about. Nanotechnology…
Mitsunori Shimura and colleagues at the R&D Center of Chiyoda Corp. (Yokohama, Japan; www.chiyoda.co.jp) have developed a new catalyst for producing a synthesis gas (syngas; hydrogen and carbon monoxide) from steam reforming of methane. The catalyst consists of precious metals…
In late 2009, Microbia PE, Inc. (Lexington, Mass.; www.microbia-pe.com) will begin commercialization of its initial carotenoid products. Microbia plans to produce β-carotene, astaxanthin, zeaxanthin, cathaxanthin and lutein — all five carotenoid products that currently have significant commercial value. These carotenoids…
When completed in early 2010, Shell Chemicals’ B.V. (The Hague, Netherlands; www.shell.com) 750,000-m.t./yr facility at the Shell Eastern Petrochemicals Complex in Singapore will be the world’s largest plant to produce mono-ethylene glycol (MEG) using Shell’s Omega process. This plant marks…
Researchers at the U.S. Dept. of Energy’s (DOE; Washington, D.C.) Ames Laboratory (www.ameslab.gov) and Iowa State University (both of Ames, Iowa) have developed a hard, smooth coating that can be applied to industrial equipment, such as pumps, gears and cutting…
Here, a design approach for continuous stirred-tank reactors is outlined for both reversible and irreversible second-order reactions Multiple CSTRs (continuous stirred-tank reactors) are advantageous in situations where the reaction is slow; two immiscible liquids are present and require higher agitation…
